Sheet Metal Brake

A brake is a metalworking machine that allows the bending of sheet metal. A cornice brake only allows for simple bends and creases.A sheet metal brake is a machine that bends metal sheets into desired shapes and sizes. The machine works by clamping the metal sheet between two dies shaped to produce the desired bend. The dies are then brought together at high speed, forcing the sheet to bend and form around them.The term “brake,” as used in modern sheet metal fabrication, comes from the Middle English verb breken, or break, which meant to bend, change direction, or deflect. You could also “break” when you drew back the string of a bow to shoot an arrow. You could even break a beam of light by deflecting it with a mirror.
